PRESTON H. ALLEN AND HENRY H. ALLEN, OF ST. LOUIS, MISSOURI, ASSIGN TO BEMIS BRO. BAG COMPANY, OF

companying drawings,. forming a part hereof:

Our invention relates tocertain new and useful improvements in fasteners for containers or envelops, and has for its special obj ect theconstruction of a fastening member which is attached to the container body, which should be imperforate to prevent the entrance of moisture or dirt into the body of the container.

In the drawings,

Figure 1 is a perspective view of a water proof container with our invention applied thereto, illustrating the fastener holding the container closed.

Fig. 2 is a central longitudinal section taken through the container or envelop, and both fastening members.

Fig. 3 is an enlarged sectional view taken through the fastener which is secured to the body of the container, with parts of the container broken away.

Fig. 4 is a similar view wherein we employ a different construction of metallic plug or rivet for making the fastener imperforate.

Fig. .5 is a sectional elevation of a split rivet which we employ, and

Fi 6 is a sectional elevation of a modified cm of rivet, which we may employ in carrying out our invention.

Referring to the drawings, 7 indicates the body of the container which is composed of waterproof material, the sides being closed by means of stitching 8. The mouth of the container is closed by means of a folded flap 2, comprising two folds 10 and 11, carrying a flap 12 which when the container is Specification of Lettersl atent.

Secured to the folded flap 9 of the contamer is a fastener which comprises ametal tubular rivet 14 provided with a flange -15 and two disks 16- and 17, the disk 16 being of heavier material than the disk 17.

These disks16and 17 are perforated and the tubular metal rivet 14 passes through the disks and also through the folds 10 and 11 of the folded flap 9, and the end of the tubular rivet 14 is upset or flanged as at 18 by means of a punclr or anysuitable mechanical device, thus securely uniting the two disks of the fastener and the fastener It is not necessary to have the fastener which is secured to the folded flap imperfo-. rate because it is not in communication with the interior of the container. El

In conjunction with the fastener just doscribed whichis' secured' to the folded flap wecmploy an imperforate fastener 19 secured to the body of the container 7. This fastening member 19 is likewise composed of a tubular rivet 14 having a flange 15 and an upset or flanged lower end 20 and two disks 16 and 17 which are secured to the body of the container in the same manner as the fastener previously described is secured to the folded flap 9 of the container.

Located in the tubular rivet or sleeve 14 is a rivet 21 provided with a head 22 overlying the flange 15 of the tubular rivet 14. The rivet 21 may be of the split type as illustrated in Figs. 2, 3 and 5, or of the hollow tubular type as illustrated in Figs. 4 and 6. The shank of the rivet 21 is of sufiicient size so as to snugly fit the tubular sleeve or rivet 14, so as to make a tight waterproof and dust proof joint, and is of sufficient length so that its lower end may be upset or flanged over the flanged end 20 of the tubular rivet 14, as illustrated in Figs. 2 and 3 wherein the lower end of the rivet 21 is flanged over the flange 20 of the hollow rivet 14 by means of a flange 23.

The upsetting of the end of the rivet 21 and forming the flange thereon, not only forms a waterproof imperforate joint, but it also has a tendency to more firmly clamp and bind the disks 16 and 17 against the body of the container. In other words, the employment of the rivet 21 and upsetting or flanging its end reinforces and strengthens the connection between the fastener disks and material located between them.
